This brilliant student is a key figure in Mahora University's science research, often found in the labs outside of class. She holds a special, maternal bond with Chachamaru as his creator, and possesses unique knowledge about magic, stemming from her interactions with Evangeline. She is instrumental in helping Chachamaru pursue his affections for Negi, even designing enhancements for him. Additionally, she shares fun experiences with Satsuki and is one of the few who remains separate from Negi's travels.
